Application filed March 31, 1820.

To all whom it may concern Be it known that I, JnNs 0. LARSEN, a citizenof the United States, and resident of St. Louis, ll lissouri, haveinvented certain new and useful Improvements in Cartons, of which thefollowing is a specification.

This invention relates to improvements in cartons, and has for itsobject a covering for dairy products such as butter, oleomargarine andlike products, the inner surface of the carton provided with an attachedlining of oiled or paratlin material which is simultaneously foldedaround the product during the same operation of the folding of thecarton.

A further object of my invention is to form a lining of approximatelythe same shape as the carton or enclosure, and a means for holding thelining intact to the carton so that the wrapping process issimultaneous.

This method dispenses with handling the product twice or more, duringthe wrapping, as the inner lining is attached to the inner face of thecarton proper.

Figure 1, is a plan view of the carton' blankp Fig. 2, is a perspectiveview of the carton in the act of being folded in shape.

F ig. 3, is a vertical sectional view of the folded or closed carton.

Fig. 1, is anenlarged view of the same. Fig. 5, is a detail sectionalview showing the fastening device by which the lining is held in place.

Fig. 6, is a. detail perspective view of a portion of the lining showingthe slit through which the fastening device is passed.

Fig. 7, is a detail perspective view of a portion of the carton showingthe'fastcniug device.

Referring to the drawings in detail 8 in dicates the blank or body of acarton, the

same being provided with scores a, 7), c, and (I, on which lines thebody is folded to a rectangular container or package.

The body is likewise provided with cross scores 6, f, a, 72., and 7:, onwhich lines the ends may be folded to form the end closures.

The blank when folded forms an elongated body consisting of four walls 9lO-11 and 12 and a flap 13, the wall 9 havlng end flaps 14 and 15, thewalls 10 and 12 each an end flap 16 arranged oppositely and each isprovided with a score j, forming tongues Serial No. 370,244.

17 which are designed to be inserted in the end closure for holding thepackage closed.

The wall 11 has end flaps 18 which are provided with lining fasteningdevices consisting of prongs 19 formed by slitting the material on thelines 20. The wall 9 is likewise provided with prongs of the sameformatlon. i

)n this flattened out blank is placed a lining 21, the same being cut inthe shape as shown by dotted lines (Figure This lining has additionalflaps is, which are the first flaps to contact with the ends of theproduct wrapped in the carton.

he lining is provided with slits 22 which are passed over the prongs 19,which hold the lining in place on the carton blank, and.

is simultaneously wrapped around the product with the carton.

n wrapping up the product the cake is placed on the wall 12 of theblank, the flap 13 is the first folded, then turning over the cake itbends the carton on the score line 0, then on Z), then on a, permittingthe prongs on the wall 9 to contact with the outer surface of the flap13.

The lining flaps 7c are then bent in on the ends of the cake, then theflaps 14 and 15 as well as the flaps 18 are bent over on top of thelining flap 7c, bringing the locking prongs 19 of the flaps 18 incontact with the upper surface of the flaps 14c and 15, then the packageis firmly closed by bending the flaps 16 over the rest of the foldedflaps and the tongue 17 inserted between the lining and wall. See Figure4:.

The fastening devices are so arranged so as not to contact with theproduct in the carton, as I may use staples, rivets or other means. ofsecuring the lining in position on the carton blank.

The essential feature of my invention however, is to form a lining onthe carton blank and by one operation wrap the product by covering itwith a lining as well as an formed on the opposite edge, a long flapformed on said edge adjacent to one of the short flaps, said flapprovided with a scored line for bending a portion of said flap incombination with a lining of oil substance placed over the blank, andV-shaped prongs formed at intervals in the body for holding the liningin position, substantially as specified.

2. A carton of the character described comprising a blank provided withtwo par allel scores running the entire length of the blank forming abody member, a plurality of scores arranged cross-wise with the blank onwhich lines the blank may be folded to encase the goods to be wrapped,one edge of the blank formed with three short flaps and one long flap,and a lining of oil substance placed over the body and flaps and prongsfor holding the same together, substantially as specified.

In testimony whereof, I have signed my name to this specification inpresence of two subscribing witnesses.
